How does pregnancy know baby anoxia?

summary

Fetal hypoxia is a very dangerous thing. Short time hypoxia may not cause any harm, but long time hypoxia will stop the development of fetus. Therefore, expectant parents should always pay attention to the state of the fetus, go to the hospital on time for examination, find abnormalities, and tell the doctor as soon as possible. How does pregnancy know baby anoxia? Let's talk about it

How does pregnancy know baby anoxia?

Fetal movement changes. Fetal movement is the normal physiological activity of the fetus. Generally, at 18-20 weeks of gestation, pregnant women can feel the activity of the fetus. The situation of different fetal movements is also different, generally speaking, the amplitude of quiet fetal movements is smaller, and the number of fetal movements is less. However, the excitatory fetal movement is large and frequent.

Abnormal fetal heart rate. Under normal circumstances, the fetal heart rate is regular, about 120-160 beats per minute. Pregnant women can use fetal heart rate monitor to observe fetal heart rate. If the fetal heart rate is abnormal, it should be repeated every 20 minutes. If the fetal heart rate is too fast, it should be repeated when there is no fetal movement. If the fetal heart rate exceeds 160 beats / min, it is the signal of fetal early hypoxia; If the fetal heart rate is less than 120 beats / min or even the fetal heart rate stops, it is the late stage of fetal hypoxia.

Fetal growth arrest. Fetal growth can be known by measuring the uterine height. Under normal circumstances, after 28 weeks of gestation, the uterine height should be increased by about 1 cm per week. If fetal hypoxia, fetal growth will be slow. Pregnant women can regularly measure the height of the uterus at home or in the hospital. If there is no increase for two weeks, they should be further examined.

matters needing attention

In pregnancy, especially in late pregnancy, pregnant mothers should not sit too long. Because the sitting position will compress the uterus, which is not conducive to the fetal activities in the abdomen. Over a long period of time, it will affect the blood circulation of the placenta, and then cause fetal hypoxia. Pregnant mothers should walk more properly, which is not only good for the fetus, but also conducive to the rise and fall of the head, and it will be more conducive to the natural birth when equal parturition.
